The temperature functions are as follows:1. Automatic recognition of working mode:The system automatically recognizes the working mode according to the start temperature/stop temperature;Start temperature Greater than stop temperature, cooling mode 'C'; start temperature Less than stop temperature, heating mode 'H'; 2. Cooling mode:When the detected temperature is greater than or equal to the starting temperature, the relay is turned on, the red indicator light is on, and the refrigeration equipment starts to work;When the detected temperature is less than or equal to the stop temperature, the relay is turned off, the red indicator light is off, and the refrigeration equipment stops working; 3. Heating mode:When the detected temperature is less than or equal to the starting temperature, the relay is turned on, the red indicator light is on, and the heating equipment starts to work;When the detected temperature ≥ the stop temperature, the relay is turned off, the red indicator light is off, and the heating equipment stops working 4. Temperature correction function OFE (-10.0℃ - 10.0℃):When the system works for a long time, there may be deviations, which can be corrected by this function, the actual temperature = measured temperature + calibration value; The humidity functions are as follows:1. Automatic recognition of working mode:The system automatically recognizes the working mode according to the start humidity/stop temperature; Start humidity Greater than stop humidity, dehumidification mode 'd'; start humidity Less than stop humidity, humidify mode 'E'; 2. Dehumidification mode:When the detected humidity is greater than or equal to the starting humidity, the relay is turned on, the green indicator light is on, and the dehumidification equipment starts to work; When the detected humidity ≤ stop humidity, the relay is turned
